aylor and Natsumi are making block towers out of large and small blocks. They are stacking the blocks on top of each other in a

frozen [14]

Answer:

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x i the height of a large block.

y is the height of a small block.

Taylor uses 4 large blocks and 2 small blocks to make a tower 63.8 inches tall.

This means that:

$4x + 2y = 63.8$

Simplifying by 2:

$2x + y = 31.9$

$y = 31.9 - 2x$

Natsumi uses 9 large blocks and 4 small blocks to make a tower 139.8 inches tall.

This means that:

$9x + 4y = 139.8$

Since $y = 31.9 - 2x$

$9x + 4(31.9 - 2x) = 139.8$

$9x + 127.6 - 8x = 139.8$

$x = 12.1$

$y = 31.9 - 2x = 31.9 - 2(12.1) = 7.7$

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.

X/-2=4, X/3+13=13, Z/2+2=4 plz show ur work and explain how u did it

AVprozaik [17]

$\dfrac{x}{-2}=4\ \ \ |multiply\ both\ sides\ by\ (-2)\\\\(-2)\cdot\dfrac{x}{-2}=(-2)\cdot4\\\\\boxed{x=-8}\\\\\dfrac{x}{3}+13=13\ \ \ |subtract\ 13\ from\ both\ sides\\\\\dfrac{x}{3}+13-13=13-13\\\\\dfrac{x}{3}=0\ \ \ |multpily\ both\ sides\ by\ 3\\\\\not3^1\cdot\dfrac{x}{\not3_1}=0\\\\\boxed{x=0}$

$\dfrac{z}{2}+2=4\ \ \ |subtract\ 2\ from\ both\ sides\\\\\dfrac{z}{2}+2-2=4-2\\\\\dfrac{z}{2}=2\ \ \ \ |multiply\ both\ sides\ by\ 2\\\\\not2^1\cdot\dfrac{z}{\not2_1}=2\cdot2\\\\\boxed{z=4}$

A box of photographs contains 13 wedding photographs 4 vacation photographs and 8 holiday photographs one is randomly selected w

ryzh [129]

Probability=desired outcomes/total possible outcomes

so
desired outcomes is the 'not wedding' photos
there are 4 vacation and 8 holiday
so 12 'not wedding' photos
12=desired outcomes

total outcomes is 13+4+8=25

so the probablity would be 12/25 or about 48%
